In-depth safety analysis
This extension can modify your experience on YouTube by reading and altering data on youtube.com. It uses the storage permission to save your preferences locally and contextMenus to add items to the right-click menu. Because its host access is tightly limited to YouTube, the permissions are minimal and expected for a tool that customizes video playback and interface.
For any YouTube enhancer, a careful user should know that extensions with host access to a site can technically observe what pages you visit and how you interact with them. In this case, the developer declares that data is not sold or used for unrelated purposes, and the privacy score is strong. Still, it's wise to apply extensions only from sources you trust and to review the permissions they ask for.
The fact sheet shows a highest-strength dimension of Maintenance & Ownership, which indicates the extension is actively updated and has a consistent track record. The weakest dimension is Publisher & Identity, suggesting limited public information about the developer. That's not unusual for independent browser tools, and it doesn't undermine the extension's solid privacy and permission practices.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
